Abstract

This paper presents the design and practical implementation of a complex impedance measurement device capable of characterization of ultrasonic transducers. The device works in the frequency range used by industrial ultrasonic transducers which is below the measurement range of modern high end network analyzers. The device uses the Goertzel algorithm instead of the more common FFT algorithm to calculate the magnitude and phase component of the impedance under test. A theoretical overview is given followed by a practical approach and measurement results.
